[0015] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] The core idea of the present invention is to configure different frequency resources for the broadcast / synchronization channels of adjacent cells and make them orthogonal to each other. At the same time, each cell is configured with its own access frequency band in advance so that the access frequency band of the adjacent cell Two-by-two orthogonality, the access frequency band will be used for channel transmission during the user's random access to the user camping process. In this way, users in adjacent cells can use different frequency band resources from the user access to the completion of the attachment process. , Which can effectively avoid the problem of co-channel interference during this period.
